B is not correct, even though it looks like. If we understand the reasoning, we will know that it does not matter whether they willing work that schedule or not, as the problem leaves you no logic reasoning to think that way. for example, if you forced to eat more, you still get fat even though you do not volunteer. D is not correct either. D casts no doubt as to whether the same schedule will work to the company's favor by improving the productivity. I do not see the link between. Pls explain. C is correct. It simply states that the high productivity is due to the fact that these already productive people can work undisturbed by co-workers. So one thing is that if everyone works the same schedule, people will be disturbed. Second, these people are already productive, as suggested by the problem. |
